Twice I've now seen this behavior. Once I was killing an AI token stack and once mine was being killed.
I have also experienced this. Once it was the repeated “-4” and another time there was a spell spiral and a destroy effect. In both cases the timeout bar happened but asking it to end the loop didn’t end the loop...
@Oktagon_Support this maybe similar to a previous post done today also. Key factor is tokens being destroyed
I encountered the same problem twice in TotP green today.
I also had Hogaak in my deck in both soft lock situations. It had to do with Hogaak!
Battle logs for both times that soft lock occurred showed Hogaak (in hand) being triggered. So the bug actually had to do with token being killed while Hogaak was in hand.
